Where is the best place to put the nest sensor?

When it comes to optimizing the efficiency and effectiveness of your home’s heating and cooling system, the placement of your Nest sensor plays a crucial role. The right location can ensure accurate temperature readings and efficient energy usage, while the wrong placement can lead to discomfort and wasted energy. In this article, we will explore the best places to put your Nest sensor, backed by research, case studies, and expert recommendations.

The Importance of Sensor Placement

Before diving into the specifics of where to place your Nest sensor, it’s essential to understand why sensor placement matters. The Nest sensor is designed to measure the temperature and humidity of its surroundings accurately. By placing it in the right location, you can ensure that it captures the most representative readings of your home’s overall climate.

Accurate temperature readings are crucial for your Nest thermostat to make informed decisions about when to heat or cool your home. Placing the sensor in an area that is too hot or too cold can lead to inefficient energy usage and discomfort for the occupants.

1. Central and Representative Locations

The best place to put your Nest sensor is in a central and representative location within your home. This ensures that it captures an accurate average temperature reading that reflects the overall climate of your living space. Placing the sensor in a peripheral area or near a heat source can lead to skewed readings and inefficient temperature control.

For example, placing the sensor near a window or a drafty area can result in inaccurate temperature readings due to the influence of external factors. Similarly, placing it near a heat source like a fireplace or a vent can lead to false temperature readings, causing your HVAC system to work harder than necessary.

By choosing a central location, such as a hallway or a living room, you can ensure that the sensor captures a more representative temperature reading, leading to better energy efficiency and comfort.

2. Avoiding Direct Sunlight and Drafts

Direct sunlight and drafts can significantly impact the accuracy of your Nest sensor’s temperature readings. Placing the sensor in direct sunlight can cause it to register higher temperatures than the actual ambient temperature, leading to unnecessary cooling. On the other hand, placing it in a drafty area can result in lower temperature readings, leading to excessive heating.

To avoid these issues, it is recommended to place the sensor away from windows, doors, and other sources of direct sunlight or drafts. This ensures that the sensor captures the true temperature of your home’s interior, allowing your Nest thermostat to make more informed decisions about heating and cooling.

3. Optimal Height and Position

The height and position of your Nest sensor also play a role in its accuracy and effectiveness. Placing the sensor at the right height and position can help it capture a more representative temperature reading and avoid interference from nearby objects.

Experts recommend placing the sensor at an average human height, around 5 feet from the ground. This height ensures that the sensor measures the temperature at a level that is most relevant to the comfort of the occupants. Placing it too high or too low can lead to inaccurate readings, as the temperature at those levels may not reflect the overall climate of the living space.

In terms of position, it is best to mount the sensor on an interior wall rather than an exterior one. Interior walls are less affected by external factors such as temperature fluctuations and drafts, providing a more stable and accurate reading.

4. Multiple Sensors for Zoned Heating and Cooling

If you have a zoned heating and cooling system or multiple floors in your home, it is advisable to use multiple Nest sensors strategically placed in different zones. This allows your Nest thermostat to optimize temperature control based on the specific needs of each zone, leading to enhanced comfort and energy efficiency.

For example, if you have a two-story home, placing a sensor on each floor can help the thermostat adjust the temperature independently for each level. This prevents unnecessary heating or cooling of unoccupied areas, saving energy and reducing utility costs.


Placing your Nest sensor in the right location is crucial for optimizing the efficiency and effectiveness of your home’s heating and cooling system. By choosing a central and representative location, avoiding direct sunlight and drafts, positioning the sensor at the optimal height and position, and using multiple sensors for zoned heating and cooling, you can ensure accurate temperature readings and efficient energy usage.

Remember, accurate temperature readings lead to better decision-making by your Nest thermostat, resulting in enhanced comfort and reduced energy consumption. Take the time to evaluate your home’s layout and needs, and place your Nest sensor accordingly to reap the benefits of a well-controlled climate and lower utility bills.
